13 Claims. (Cl. 221-60) This invention relates'to new andlimproved form of package for pastes or'plastic materials, more particularly food staffs of this character.

Anobject of the invention is to provide a cap for a collapsible tube or the like having associated therewith an extrusion nozzle through which the material may be extruded in a desired shape.

One feature of my invention is the provision of a package arrangement including a plurality of extrusion nozzles having variously shaped orifices, and arranged so that any one or com- 7 bination of two or more nozzles-may be used at one time in a simple, efllcient and sanitaryman- 1. her.

- It is frequently desirable the use of certain processed-plastic foods suchas pastes of cheese.

fish, or meat, or sugar icings and the like tov apply these materials to a surface'ofsome other lfood material such as crackers, pastry .or bread in a decorative extruded form. 3

1 In a package according to my invention several types of nozzles may-be included with a collapsible container as sold, and the user may then simply open the package and remove the nozzles which are not to be used. 'Upon leaving or'replacing the selected nozzle one may directly squeeze the material from the collapsible container in the desired extruded shape.

Further features and advantages of my invention will be readily apparent from the following descriptionof the embodiments illustrated in the drawing, in which:

Figure 1 is a longitudinal section through the I center of the discharge end of a package as prepared for sale.

Figure 2 is a similar view through a package which has been opened and is ready for use.

Figure 3 is a plan view of an extrusion nozzle having a round orifice.

Figure 4 is a plan view of another nozzle adapted to extrude a crinkly ribbon of material.

Figure 5 is a plan view of a nozzle having another form of orifice.

46 Figure 6 is an end elevation of a package showing a fourth extrusion nozzle in operative position to extrude a ribbon shaped length of material.

Figure 7 is a view similar to'Figure-l showing another embodiment of my invention in which the extrusion nozzles are simply disc shaped, and

Figure 8 is a view similar to Fig. 2 showing a disc shaped extrusion nozzle in operative position.

My invention is preferably applied to an extruded collapsible tube l0 formed oftin, alu- 'minum, or the like-and having a neck portion II which is threaded onthe outside to receive.

a cap l2. Insteadof using a cap as the sealing means for the opening in the neck ll, my im- .6 proved cap has an opening l3 in its top to receive the crowns of a series of cup shaped extrusion nozzles ll. A

In the preferred embodiment of my invention these extrusion nozzles are arranged insets 10 adapted to benested together as shown in Fig; '1'. Each nozzle preferably has an opening of different shape such as shown in Figs. 3 and 6. It will be understood that these openings maybe of any desired configuration. The neck of the'col- 5 lapsible tube may be provided with a sealing partition l5 at its end formedthereon in the course of extruding the tube. When the package is to be used, the cap and extrusion nozzles II are removed and this partition I5 is then punc- 20 tured with some sharp instrument, such as an ice pick. The extrusion nozzle it having the desired shape of opening may then be fitted into the cap and the cap replaced on the neck H.

-The plastic food or the like may then be extruded 5 through the orifice in the selected extrusion nozzle by simplysqueezing the collapsible container I0.

In initially assembling the package, I prefer to include a plain disc l6 which may be used to 30 I seal the opening in the partition l5 after this partition has been punctured. After the package has been used to extrude some of the, material therein, it is a very simple matter to rinse the extrusion nozzles, if necessary, and replace 5 them, together with the plain disc IS, in the cap l2 which is then screwed on in place. If desired, the partition l5 might be provided originally with an opening and the disc l6 would then be relied upon to effect the seal as the package is 40 shipped. If the openings in nozzles M are of suitable configuration to jointly close the open- 'ing in the cap completely, the disc l6 may be face of the cap I! (Fig. 2). By providing nozzles of this shape the extruded paste strip is positively prevented from contacting the outside of the cap duringuse.

These extrusion nozzles may be made of metal, such as tin, aluminum and the like, or other material by a simple stamping operation which forms the cup shape portions l1 and the orifices in a single step or they may be made in any other convenient manner.

While the extrusion nozzles areshown with flanges at right angle to the walls of the cup shaped portions, the. latter may be tapered inwardly from the former so that these various nozzles may be made to nest even though they are of the same size. Such an arrangement, how- 1 ever, is likely to cause the different nozzles to wedge together. if the cap should be screwed too tightly in place and therefore the form illustrated is preferred.

Another embodiment of my invention is illustrated in Figs. 7 and 8 for use with a tube Ill having a neck I I which is formed without the integral closureor partition l5. In this embodiment of my invention I employ simple fiat discshaped extrusion nozzles l8. Any desired number of these fiat; discs It may be employed with or withouta sealing disc IS. The use of these modified containers will be substantially the same as described above. The fiat nozzles are not so satisfactory when the tubes are closed by the partitions l5 since nospace is then provided between the irregular opening punched in the partition and the opening intended to control the design. The provision'of such a space, as in Fig.

2, insures proper formation of the extruded strip without particular care in puncturing the partition. 1

If desired the form of the openings in the various nozzles may be such that artistic configurationswill be produced not only by theindividual nozzles but also by combination of two or more nozzles; Thus provision may be made for a greater number of designs than the nozzles provided. Furthermore, two or more nozzles may fit together in difierent positions to produce different designs. Whenever it is desired to arrange the nozzles in definite relations they may be provided with interfitting projections and recesses, as by indenting a portion of the wall of each nozzle.

It is also possible to practice my invention, in part, by means of separate andindividual extrusion nozzles which may be threaded so that they may be screwed on the neck II in place of the cap or by employing caps for the package in which the openings 13 are shaped to provide the desired extruded form of material.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any I equivalents of the features shown and described or portions thereof, but recognize that various modifications are possible within the scope of the invention claimed.
